When the site became overloaded this week, AirNow started redirecting users to parts of the old site to spread out the traffic. But some of the new links didn’t work on the old site and some of the old maps wouldn’t load. So AirNow decided to revert fully to the old site, which has made the service more stable.\u003c/p>\n\u003cp>It’s not just AirNow site that’s struggled to meet the demand. \u003ca href=\"http://www.baaqmd.gov/\" target=\"_blank\" rel=\"noopener\">The Bay Area Air Quality Management District’s website\u003c/a> has been getting 300,000 page views per day, according to a spokesperson, a 6,000 percent increase in traffic.

AirNow, for instance, is back to providing AQIs on a more granular geographical level.\u003c/p>\n\u003cp>The other good news: There are other places to get your air quality information, if one site isn’t loading.\u003c/p>\n\u003cp>Some options:\u003c/p>\n\u003cul>\n\u003cli>AirNow partnered with the\u003ca href=\"https://sites.google.com/firenet.gov/wfaqrp-external/home\" target=\"_blank\" rel=\"noopener\"> U.S. Forest Service’s Wildland Fire Air Quality Response Program\u003c/a> to send users to its site when necessary.

The difference, though, is PurpleAir provides rolling updates—so the AQI is the most recent 80-second average—whereas the AQI on AirNow or BAAQMD is often a 24-hour average with an hourly estimate based on calculations. PurpleAir uses a different type of monitor, a cheaper and more portable laser particle counter, which can read slightly higher than sensors that measure particulate matter by mass concentration.\u003c/li>\n\u003cli>\u003ca href=\"https://www.kqed.org/science/1930023/map-heres-your-daily-air-quality-report-for-the-bay-area\" target=\"_blank\" rel=\"noopener\">KQED’s map\u003c/a> is updated hourly, based on the open data from AirNow, and includes info about the air quality categories.\u003c/li>\n\u003cli>You can also try \u003ca href=\"https://airnow.gov/index.cfm?action=airnow.local_city&zipcode=94102&submit=Go\" target=\"_blank\" rel=\"noopener\">the AirNow website\u003c/a> again.

Most of us have been clicking on the EPA’s air quality website,\u003ca href=\"https://airnow.gov/\" target=\"_blank\" rel=\"noopener\"> AirNow,\u003c/a> which allows you to type in your zip code and see the Air Quality Index (AQI) for your area.

You are depriving people from accessing crucial info that will affect their health. Hire adequate developers who would run it normally.\u003c/p>\n\u003cp>One of the factors affecting the site’s performance was that AirNow upgraded to a new interface in September, and the site’s expanded functionality required more server resources. When the site became overloaded this week, AirNow started redirecting users to parts of the old site to spread out the traffic. But some of the new links didn’t work on the old site and some of the old maps wouldn’t load. So AirNow decided to revert fully to the old site, which has made the service more stable.\u003c/p>\n\u003cp>It’s not just AirNow site that’s struggled to meet the demand. \u003ca href=\"http://www.baaqmd.gov/\" target=\"_blank\" rel=\"noopener\">The Bay Area Air Quality Management District’s website\u003c/a> has been getting 300,000 page views per day, according to a spokesperson, a 6,000 percent increase in traffic. The agency had to increase server and database capacity to handle the load.\u003c/p>\n\u003cp>\u003ca href=\"https://www.purpleair.com/\" target=\"_blank\" rel=\"noopener\">PurpleAir\u003c/a>, which is a small private company that creates portable personal air monitors and uses a wi-fi open source network to map the air quality via that equipment, also succumbed to traffic overload Thursday night.\u003c/p>\n\u003cp>\u003c/p>\u003cp>\u003c/p>\u003cp>”This is much bigger than expected. Through the fires this summer we did not experience this sort of traffic,” said Amanda Hawkins, one of the company’s founders.\u003c/p>\n\u003cp>The good news: Most of the sites have now upgraded their back-ends to handle the traffic. AirNow, for instance, is back to providing AQIs on a more granular geographical level.\u003c/p>\n\u003cp>The other good news: There are other places to get your air quality information, if one site isn’t loading.\u003c/p>\n\u003cp>Some options:\u003c/p>\n\u003cul>\n\u003cli>AirNow partnered with the\u003ca href=\"https://sites.google.com/firenet.gov/wfaqrp-external/home\" target=\"_blank\" rel=\"noopener\"> U.S. Forest Service’s Wildland Fire Air Quality Response Program\u003c/a> to send users to its site when necessary. The U.S. Forest Service increased their service capacity Thursday to take on some of the additional traffic. \u003ca href=\"https://tools.airfire.org/monitoring/v4/#!/?category=PM2.5_nowcast¢erlat=42¢erlon=-95&zoom=4\" target=\"_blank\" rel=\"noopener\">See the U.S. Forest Service’s Air Monitoring site here\u003c/a>.\u003c/li>\n\u003cli>The California Air Resources Board also runs a \u003ca href=\"https://mobile.arb.ca.gov/breathewell/CityList.aspx\" target=\"_blank\" rel=\"noopener\">Breathewell site\u003c/a> designed for mobile users.\u003c/li>\n\u003cli>\u003ca href=\"http://www.baaqmd.gov/\" target=\"_blank\" rel=\"noopener\">BAAQMD.gov\u003c/a> increased its server capacity and provides an air quality map, as well as pure data. The 31 actual air monitors around the Bay Area that feed the AirNow site come from BAAQMD.\u003c/li>\n\u003cli>The World Air Quality Index is a global project, based in Beijing, that provides AQI information for 1,000 cities around the world. You can view the\u003ca href=\"http://aqicn.org/city/california/san-francisco/san-francisco-arkansas-street/\" target=\"_blank\" rel=\"noopener\"> AQI at the nearest station to you\u003c/a>.\u003c/li>\n\u003cli>\u003ca href=\"https://www.purpleair.com/map#1/25/-30\" target=\"_blank\" rel=\"noopener\">PurpleAir\u003c/a> also provides a map made up of data from its own network of personal air monitors. The difference, though, is PurpleAir provides rolling updates—so the AQI is the most recent 80-second average—whereas the AQI on AirNow or BAAQMD is often a 24-hour average with an hourly estimate based on calculations. PurpleAir uses a different type of monitor, a cheaper and more portable laser particle counter, which can read slightly higher than sensors that measure particulate matter by mass concentration.\u003c/li>\n\u003cli>\u003ca href=\"https://www.kqed.org/science/1930023/map-heres-your-daily-air-quality-report-for-the-bay-area\" target=\"_blank\" rel=\"noopener\">KQED’s map\u003c/a> is updated hourly, based on the open data from AirNow, and includes info about the air quality categories.\u003c/li>\n\u003cli>You can also try \u003ca href=\"https://airnow.gov/index.cfm?action=airnow.local_city&zipcode=94102&submit=Go\" target=\"_blank\" rel=\"noopener\">the AirNow website\u003c/a> again.

These environmental factors could affect new shell hardening after a molt, he said.\u003c/p>\n\u003cp>Increasing levels of carbon dioxide in the atmosphere mean more of the gas becomes dissolved in the ocean, especially near the surface where crabs live. In water, carbon dioxide becomes carbonic acid, which breaks down crustacean shells. Warmer temperatures accelerate these reactions.\u003c/p>\n\u003cp>For now, conditions are still in the livable range for crabs and their relatives, Mykles said. “We don’t really know where that threshold is.”\u003c/p>\n\u003cp>The more imminent climate-change worry with crabs is about the plankton that make up their diets. These single-celled organisms are the source of the calcium carbonate critical to shell formation and are more vulnerable to changing ocean conditions.\u003c/p>\n\u003cp>Unlike their tastier cousins, Mykles’ blackback crabs spend most of their lives on land. Females return to the sea only briefly to lay their eggs.\u003c/p>\n\u003cp>On the sand-dune beaches where they live, the males do constant battle over territory. The stakes are high: If one of these baby-faced crabs secures a winning spot, he can invite a mate into his den, 6 or 7 feet beneath the surface.\u003c/p>\n\u003cfigure id=\"attachment_1933544\" class=\"wp-caption aligncenter\" style=\"max-width: 720px\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1933544\" src=\"https://ww2.kqed.org/science/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_crabfight-grab_720.gif\" alt=\"\" width=\"720\" height=\"405\">\u003cfigcaption class=\"wp-caption-text\">Blackback land crabs can tear each other apart in their battles for territory. \u003ccite>(Alex Jones)\u003c/cite>\u003c/figcaption>\u003c/figure>\n\u003cp>With all this roughhousing, more than feelings get hurt. “These crabs are not very nice. They live in large colonies. They attack each other, and they’ll eat each other,” Mykles said.\u003c/p>\n\u003cp>The male crabs inevitably lose limbs and damage their shells in constant dust-ups. Luckily, like many other arthropods, a group that includes insects and spiders, these crabs can release a leg or claw voluntarily if threatened. It’s not unusual to see animals in the field missing two or three walking legs.\u003c/p>\n\u003cp>The limbs regrow at the next molt, which is typically once a year for an adult. When a molt cycle begins, tiny limb buds form where a leg or a claw has been lost. Over the next six to eight weeks, the buds enlarge while the crab reabsorbs calcium from its old shell and secretes a new, paper-thin one underneath.\u003c/p>\n\u003cp>In the last hour of the cycle, the crab gulps air to create enough internal pressure to pop open the top of its shell, called the carapace. As the crab pushes its way out, the same internal pressure helps uncoil the new legs. The replacement shell thickens and hardens, and the crab eats the old shell.\u003c/p>\n\u003cfigure id=\"attachment_1933542\" class=\"wp-caption aligncenter\" style=\"max-width: 800px\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-1933542\" src=\"https://ww2.kqed.org/science/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-800x450.jpg\" alt=\"\" width=\"800\" height=\"450\" srcset=\"https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-800x450.jpg 800w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-160x90.jpg 160w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-768x432.jpg 768w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-1020x574.jpg 1020w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-1200x675.jpg 1200w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-1920x1080.jpg 1920w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-1180x664.jpg 1180w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-960x540.jpg 960w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-240x135.jpg 240w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-375x211.jpg 375w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-520x293.jpg 520w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\">\u003cfigcaption class=\"wp-caption-text\">During a crab’s molt cycle, tiny buds sprout in the sockets where it lost legs. \u003ccite>(Alex Jones)\u003c/cite>\u003c/figcaption>\u003c/figure>\n\u003cp>The clues about how to produce molting on demand have been stacking up for decades.\u003c/p>\n\u003cp>It turns out that the control center lies in an unexpected place: the crab’s eyestalks, where a master nerve cluster like the human pituitary gland orders up a cocktail of hormones from an array of secondary glands.\u003c/p>\n\u003cp>Because of the location of this so-called X-organ, identified in the 1950s, Mykles and others have guessed that visual cues, like the number of nearby crabs or the length of daylight, could play a role in determining when it’s time for a change of shell.\u003c/p>\n\u003cp>What’s more, the hormones from X-organ don’t induce molting — they prevent it. Without the enzymes that keep molting in check, a crab would be constantly cycling through new shells. Such unbridled molting is fatal to a crab — after a few rounds, they get stuck trying to get out of the last shell.\u003c/p>\n\u003cp>In the 1970s, Dorothy Skinner at Oak Ridge National Laboratory in Tennessee hit on something else. Despite its very small brain, the blackback can count, at least when it comes to its legs. Consistently, her research found, if a crab loses five legs or more, molting starts ahead of schedule.\u003c/p>\n\u003cp>While these discoveries relied on classic scientific approaches, such as behavioral studies, the current work in the Crab Lab employs newly developed gene-based tools.

These environmental factors could affect new shell hardening after a molt, he said.\u003c/p>\n\u003cp>Increasing levels of carbon dioxide in the atmosphere mean more of the gas becomes dissolved in the ocean, especially near the surface where crabs live. In water, carbon dioxide becomes carbonic acid, which breaks down crustacean shells. Warmer temperatures accelerate these reactions.\u003c/p>\n\u003cp>For now, conditions are still in the livable range for crabs and their relatives, Mykles said. “We don’t really know where that threshold is.”\u003c/p>\n\u003cp>The more imminent climate-change worry with crabs is about the plankton that make up their diets. These single-celled organisms are the source of the calcium carbonate critical to shell formation and are more vulnerable to changing ocean conditions.\u003c/p>\n\u003cp>Unlike their tastier cousins, Mykles’ blackback crabs spend most of their lives on land. Females return to the sea only briefly to lay their eggs.\u003c/p>\n\u003cp>On the sand-dune beaches where they live, the males do constant battle over territory. The stakes are high: If one of these baby-faced crabs secures a winning spot, he can invite a mate into his den, 6 or 7 feet beneath the surface.\u003c/p>\n\u003cfigure id=\"attachment_1933544\" class=\"wp-caption aligncenter\" style=\"max-width: 720px\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1933544\" src=\"https://ww2.kqed.org/science/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_crabfight-grab_720.gif\" alt=\"\" width=\"720\" height=\"405\">\u003cfigcaption class=\"wp-caption-text\">Blackback land crabs can tear each other apart in their battles for territory. \u003ccite>(Alex Jones)\u003c/cite>\u003c/figcaption>\u003c/figure>\n\u003cp>With all this roughhousing, more than feelings get hurt. “These crabs are not very nice. They live in large colonies. They attack each other, and they’ll eat each other,” Mykles said.\u003c/p>\n\u003cp>The male crabs inevitably lose limbs and damage their shells in constant dust-ups. Luckily, like many other arthropods, a group that includes insects and spiders, these crabs can release a leg or claw voluntarily if threatened. It’s not unusual to see animals in the field missing two or three walking legs.\u003c/p>\n\u003cp>The limbs regrow at the next molt, which is typically once a year for an adult. When a molt cycle begins, tiny limb buds form where a leg or a claw has been lost. Over the next six to eight weeks, the buds enlarge while the crab reabsorbs calcium from its old shell and secretes a new, paper-thin one underneath.\u003c/p>\n\u003cp>In the last hour of the cycle, the crab gulps air to create enough internal pressure to pop open the top of its shell, called the carapace. As the crab pushes its way out, the same internal pressure helps uncoil the new legs. The replacement shell thickens and hardens, and the crab eats the old shell.\u003c/p>\n\u003cfigure id=\"attachment_1933542\" class=\"wp-caption aligncenter\" style=\"max-width: 800px\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-1933542\" src=\"https://ww2.kqed.org/science/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-800x450.jpg\" alt=\"\" width=\"800\" height=\"450\" srcset=\"https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-800x450.jpg 800w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-160x90.jpg 160w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-768x432.jpg 768w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-1020x574.jpg 1020w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-1200x675.jpg 1200w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-1920x1080.jpg 1920w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-1180x664.jpg 1180w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-960x540.jpg 960w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-240x135.jpg 240w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-375x211.jpg 375w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/11/DL520_BlackbackCrabs_limb-bud-xcu_CC-520x293.jpg 520w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\">\u003cfigcaption class=\"wp-caption-text\">During a crab’s molt cycle, tiny buds sprout in the sockets where it lost legs. \u003ccite>(Alex Jones)\u003c/cite>\u003c/figcaption>\u003c/figure>\n\u003cp>The clues about how to produce molting on demand have been stacking up for decades.\u003c/p>\n\u003cp>It turns out that the control center lies in an unexpected place: the crab’s eyestalks, where a master nerve cluster like the human pituitary gland orders up a cocktail of hormones from an array of secondary glands.\u003c/p>\n\u003cp>Because of the location of this so-called X-organ, identified in the 1950s, Mykles and others have guessed that visual cues, like the number of nearby crabs or the length of daylight, could play a role in determining when it’s time for a change of shell.\u003c/p>\n\u003cp>What’s more, the hormones from X-organ don’t induce molting — they prevent it. Without the enzymes that keep molting in check, a crab would be constantly cycling through new shells. Such unbridled molting is fatal to a crab — after a few rounds, they get stuck trying to get out of the last shell.\u003c/p>\n\u003cp>In the 1970s, Dorothy Skinner at Oak Ridge National Laboratory in Tennessee hit on something else. Despite its very small brain, the blackback can count, at least when it comes to its legs. Consistently, her research found, if a crab loses five legs or more, molting starts ahead of schedule.\u003c/p>\n\u003cp>While these discoveries relied on classic scientific approaches, such as behavioral studies, the current work in the Crab Lab employs newly developed gene-based tools. In particular, High-Throughput Sequencing or HTS, which tracks which crab genes are most active at different points in the molt cycle, is opening a lot of avenues of research.\u003c/p>\n\u003cp>\u003c/p>\u003c/div>",

And we know some scientists spend a lot of time figuring out how much extra heat we get from all the concrete in urban areas – it’s called the heat island effect, and it makes a city core hotter than the surrounding area. But none of that shows exactly what people are experiencing in their homes, which is where they are likely to begin to feel sick from heat. We wanted to know what the heat was like at home, especially at night when people’s bodies need a chance to cool off. \u003c/span>\u003c/p>\n\u003cp>\u003cb>\u003c/p>\u003cp>\u003c/p>\u003cp>How we found people who might be at risk\u003c/b>\u003c/p>\n\u003cp>\u003cspan style=\"font-weight: 400;\">We did it with shoe leather and flyers. We looked for people who are medically vulnerable (elderly or with pre-existing conditions) and people who are socially vulnerable – who have no air conditioning, for example, and can’t afford to buy it. Some studies identify African-Americans, Latinos and immigrants as vulnerable. My brother-in-law translated a flyer into Korean; we did them in Spanish and Vietnamese, too. I became like a traveling salesman – emails, calls, flyers, senior centers, churches – no group too small to visit. Is there a name for driving all the way around the southern half of the bay in one day?

"headTitle": "Should Self-Driving Cars Have Ethics? | KQED",
"content": "\u003cp>In the not-too-distant future, fully autonomous vehicles will drive our streets. These cars will need to make split-second decisions to avoid endangering human lives — both inside and outside of the vehicles.[contextly_sidebar id=”A72R30LrDpzQR8fTZBZlpUjzNz65l8Ib”]\u003c/p>\n\u003cp>To determine attitudes toward these decisions a group of researchers created a variation on the classic philosophical exercise known as “\u003ca href=\"https://www.nytimes.com/2013/11/24/books/review/would-you-kill-the-fat-man-and-the-trolley-problem.html?_r=0\" target=\"_blank\" rel=\"noopener\">the Trolley problem\u003c/a>.” They posed a series of moral dilemmas involving a self-driving car with brakes that suddenly give out: Should the car swerve to avoid a group of pedestrians, killing the driver? Or should it kill the people on foot, but spare the driver? Does it matter if the pedestrians are men or women? Children or older people? Doctors or bank robbers?\u003c/p>\n\u003cp>To pose these questions to a large range of people, the researchers built a website called \u003ca href=\"http://moralmachine.mit.edu/\" target=\"_blank\" rel=\"noopener\">Moral Machine\u003c/a>, where anyone could click through the scenarios and say what the car should do. “Help us learn how to make machines moral,” \u003ca href=\"https://www.youtube.com/watch?time_continue=44&v=XCO8ET66xE4\" target=\"_blank\" rel=\"noopener\">a video\u003c/a> implores on the site.\u003c/p>\n\u003cp>The grim game went viral, multiple times over.\u003c/p>\n\u003cp>“Really beyond our wildest expectations,” says Iyad Rahwan, an associate professor of Media Arts and Sciences at the MIT Media Lab, who was one of the researchers. “At some point we were getting 300 decisions per second.”\u003c/p>\n\u003cp>[ad fullwidth]\u003c/p>\n\u003cp>What the researchers found was a series of near-universal preferences, regardless of where someone was taking the quiz. On aggregate, people everywhere believed the moral thing for the car to do was to spare the young over the old, spare humans over animals, and spare the lives of many over the few. Their findings, led by by MIT’s Edmond Awad, were \u003ca href=\"https://www.nature.com/articles/s41586-018-0637-6.epdf?referrer_access_token=uU4x-rhlVAN5T3IHKOMA49RgN0jAjWel9jnR3ZoTv0OR8PKa5Kws8ZzsJ9c7-2Qp8nbIwouAM66OQiCFCUYXQcLjiRp8hq1Mu0OOkJm9KQNIIgiR_QnHTgfkYXdiYutiyp5ICo21HAmgq0VHt9U28RB0yiBu-JbVZDOiCsUlIOEq0rzBQzY3TMkqbs2JWr1fd2DaznfOPEMcs85CSUlgLHsk8py2Ok2vXJZM6-1e2Wo%3D&tracking_referrer=seamus.npr.org\" target=\"_blank\" rel=\"noopener\">published \u003c/a>Wednesday in the journal \u003cem>Nature.[contextly_sidebar id=”5UDJZzcQefNHiXDmvuIEJ4VrY3JR2DLV”]\u003c/em>\u003c/p>\n\u003cp>Using geolocation, researchers found that the 130 countries with more than 100 respondents could be grouped into three clusters that showed similar moral preferences. Here, they found some variation.\u003c/p>\n\u003cp>For instance, the preference for sparing younger people over older ones was much stronger in the Southern cluster (which includes Latin America, as well as France, Hungary, and the Czech Republic) than it was in the Eastern cluster (which includes many Asian and Middle Eastern nations). And the preference for sparing humans over pets was weaker in the Southern cluster than in the Eastern or Western clusters (the latter includes, for instance, the U.S., Canada, Kenya, and much of Europe).\u003c/p>\n\u003cp>And they found that those variations seemed to correlate with other observed cultural differences. Respondents from collectivistic cultures, which “emphasize the respect that is due to older members of the community,” showed a weaker preference for sparing younger people.\u003c/p>\n\u003cp>Rawhan emphasized that the study’s results should be used with extreme caution, and they shouldn’t be considered the final word on societal preferences — especially since respondents were not a representative sample. (Though the researchers did conduct statistical correction for demographic distortions, reweighing the responses to match a country’s demographics.)\u003c/p>\n\u003cp>What does this add up to?

These cars will need to make split-second decisions to avoid endangering human lives — both inside and outside of the vehicles.\u003c/p>\u003cp>\u003c/p>\u003cp>\u003c/p>\n\u003cp>To determine attitudes toward these decisions a group of researchers created a variation on the classic philosophical exercise known as “\u003ca href=\"https://www.nytimes.com/2013/11/24/books/review/would-you-kill-the-fat-man-and-the-trolley-problem.html?_r=0\" target=\"_blank\" rel=\"noopener\">the Trolley problem\u003c/a>.” They posed a series of moral dilemmas involving a self-driving car with brakes that suddenly give out: Should the car swerve to avoid a group of pedestrians, killing the driver? Or should it kill the people on foot, but spare the driver? Does it matter if the pedestrians are men or women? Children or older people? Doctors or bank robbers?\u003c/p>\n\u003cp>To pose these questions to a large range of people, the researchers built a website called \u003ca href=\"http://moralmachine.mit.edu/\" target=\"_blank\" rel=\"noopener\">Moral Machine\u003c/a>, where anyone could click through the scenarios and say what the car should do. “Help us learn how to make machines moral,” \u003ca href=\"https://www.youtube.com/watch?time_continue=44&v=XCO8ET66xE4\" target=\"_blank\" rel=\"noopener\">a video\u003c/a> implores on the site.\u003c/p>\n\u003cp>The grim game went viral, multiple times over.\u003c/p>\n\u003cp>“Really beyond our wildest expectations,” says Iyad Rahwan, an associate professor of Media Arts and Sciences at the MIT Media Lab, who was one of the researchers. “At some point we were getting 300 decisions per second.”\u003c/p>\n\u003cp>\u003c/p>\u003c/div>",

On aggregate, people everywhere believed the moral thing for the car to do was to spare the young over the old, spare humans over animals, and spare the lives of many over the few. Their findings, led by by MIT’s Edmond Awad, were \u003ca href=\"https://www.nature.com/articles/s41586-018-0637-6.epdf?referrer_access_token=uU4x-rhlVAN5T3IHKOMA49RgN0jAjWel9jnR3ZoTv0OR8PKa5Kws8ZzsJ9c7-2Qp8nbIwouAM66OQiCFCUYXQcLjiRp8hq1Mu0OOkJm9KQNIIgiR_QnHTgfkYXdiYutiyp5ICo21HAmgq0VHt9U28RB0yiBu-JbVZDOiCsUlIOEq0rzBQzY3TMkqbs2JWr1fd2DaznfOPEMcs85CSUlgLHsk8py2Ok2vXJZM6-1e2Wo%3D&tracking_referrer=seamus.npr.org\" target=\"_blank\" rel=\"noopener\">published \u003c/a>Wednesday in the journal \u003cem>Nature.\u003c/p>\u003cp>\u003c/p>\u003cp>\u003c/em>\u003c/p>\n\u003cp>Using geolocation, researchers found that the 130 countries with more than 100 respondents could be grouped into three clusters that showed similar moral preferences. Here, they found some variation.\u003c/p>\n\u003cp>For instance, the preference for sparing younger people over older ones was much stronger in the Southern cluster (which includes Latin America, as well as France, Hungary, and the Czech Republic) than it was in the Eastern cluster (which includes many Asian and Middle Eastern nations). And the preference for sparing humans over pets was weaker in the Southern cluster than in the Eastern or Western clusters (the latter includes, for instance, the U.S., Canada, Kenya, and much of Europe).\u003c/p>\n\u003cp>And they found that those variations seemed to correlate with other observed cultural differences. Respondents from collectivistic cultures, which “emphasize the respect that is due to older members of the community,” showed a weaker preference for sparing younger people.\u003c/p>\n\u003cp>Rawhan emphasized that the study’s results should be used with extreme caution, and they shouldn’t be considered the final word on societal preferences — especially since respondents were not a representative sample. (Though the researchers did conduct statistical correction for demographic distortions, reweighing the responses to match a country’s demographics.)\u003c/p>\n\u003cp>What does this add up to?

"content": "\u003cp>In his latest attack on California’s forest management policies, President Donald Trump claimed on Tuesday that the solution to the state’s punishing wildfire season should be a no-brainer.\u003c/p>\n\u003cp>“We’re tired of giving California hundreds and hundreds of millions of dollars, all the time for their forest fires,” Trump told the White House State Leadership Day Conference, “when you wouldn’t have them if they managed their forests properly. They don’t.”\u003c/p>\n\u003cp>Leaving aside the fact that nearly 60 percent of California’s forestland is managed by the federal government, most scientists agree that the buildup of fuels is a factor in fire severity.\u003c/p>\n\u003cp>But it’s not nearly that simple.\u003c/p>\n\u003cp>Firefighters on the ground know that fire behaves very differently depending on whether the flames are spreading in grass, chaparral, forest, or a mix. And according to fire scientists, property owners and policymakers should be paying more attention to these differences, too.\u003c/p>\n\u003cp>\u003cstrong>Building the Campfire\u003c/strong>\u003c/p>\n\u003cp>If you’ve ever built a campfire, you know that you need different kinds of fuel to get a fire going: paper, small twigs, or pine needles to ignite the fire, then small sticks to keep it going, and finally big logs that keep the fire going and produce the big flames that keep you warm all night.\u003c/p>\n\u003cp>Wildfires work the same way.\u003c/p>\n\u003cp>Firefighters categorize plants based on their size and how quickly they dry out — and consequently, how easily they will ignite and burn. Grasses are 1-hour fuels, sometimes called light fuels, or flashy fuels. If the weather becomes hot and dry, they become just as dry as the surrounding atmosphere in about an hour. Trees and dead logs and are usually 100 or 1000-hour fuels; it takes much longer before they’re ready to burn, but when they get going they can give off bigger flames, more intense heat, and can burn for a long time.\u003c/p>\n\u003cfigure id=\"attachment_1930109\" class=\"wp-caption alignnone\" style=\"max-width: 800px\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-1930109\" src=\"https://ww2.kqed.org/science/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-800x566.png\" alt=\"\" width=\"800\" height=\"566\" srcset=\"https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-800x566.png 800w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-160x113.png 160w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-768x543.png 768w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-1020x721.png 1020w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-1200x849.png 1200w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-1920x1358.png 1920w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-1180x834.png 1180w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-960x679.png 960w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-240x170.png 240w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-375x265.png 375w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-520x368.png 520w\" sizes=\"(max-width: 800px) 100vw, 800px\">\u003cfigcaption class=\"wp-caption-text\">As of August 16, the Mendocino Complex had burned over 370,000 acres.

That’s why, as the fire season progresses, it’s kind of a continuing threat that kind of multiplies as those heavier fuels dry out.”\u003c/p>\n\u003cp>\u003cstrong>The Trouble with Grasses\u003c/strong>\u003c/p>\n\u003cp>It might seem like light fuels — like grasses — are preferable to heavy forest fuels or dense shrublands.

Grasses are 1-hour fuels, sometimes called light fuels, or flashy fuels. If the weather becomes hot and dry, they become just as dry as the surrounding atmosphere in about an hour. Trees and dead logs and are usually 100 or 1000-hour fuels; it takes much longer before they’re ready to burn, but when they get going they can give off bigger flames, more intense heat, and can burn for a long time.\u003c/p>\n\u003cfigure id=\"attachment_1930109\" class=\"wp-caption alignnone\" style=\"max-width: 800px\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-1930109\" src=\"https://ww2.kqed.org/science/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-800x566.png\" alt=\"\" width=\"800\" height=\"566\" srcset=\"https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-800x566.png 800w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-160x113.png 160w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-768x543.png 768w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-1020x721.png 1020w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-1200x849.png 1200w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-1920x1358.png 1920w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-1180x834.png 1180w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-960x679.png 960w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-240x170.png 240w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-375x265.png 375w, https://cdn.kqed.org/wp-content/uploads/sites/35/2018/08/KQEDScience_Mendocino_768-520x368.png 520w\" sizes=\"(max-width: 800px) 100vw, 800px\">\u003cfigcaption class=\"wp-caption-text\">As of August 16, the Mendocino Complex had burned over 370,000 acres.

The reverse is also true: if you change the amount of fire, you can change the type of fuel.\u003c/p>\n\u003cp>For example, native grasslands and woodlands \u003ca href=\"http://www.publish.csiro.au/wf/WF05003\">once flourished in the Bay Area\u003c/a>, maintained by regular cultural burns by Native Americans and by grazing. A reduction in grazing, as well as the end of these traditional burns, led to the conversion of grassland to shrubland and an increase in heavy fuels in some areas.
